Installation of Tekonsha Brake Controller Adapter

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

2002 Chevrolet Silverado

The hitch and controller was installed on a 2002 Chevy 2500HD. It took roughly 15 min to install the Tekonsha P3 Brake Controller, plug it in and program it. As far as the B&W Turnover Ball Hitch, I cut the hole in the bed and cut the heat shield out the day before while I was waiting for the hitch to arrive. The next day my parts arrived, I laid out all the parts to make sure everything was there and then started the install. I didn't want to cut the 1"x1/2" notch out of my fender well to get the angle iron in so I spent about 15 min. trying to get it up on top the frame from underneath the truck. A waste of time. Do like the instructions say, cut the notch and slide it straight across the top of the frame. It will save time and aggravation. After getting both braces in place I ran a piece of rope down thru the hole and pulled the hitch plate up into place and tied it off. I installed all the bolts finger tight, put the side plates on and tightened everything up. It looks nice and I saved myself a $435.00 installation fee. With out a lift and without taking my rear tires off it took about 3 1/2 hrs. to install by myself. The only thing I want to say to B&W is don't place the heavy metal hitch parts on the booklet with the packets of Lithium Grease in it, they bust as the picture shows. Last but not least, thank you Sherry for all your help with my order and getting it to me quick in such short notice. I really appreciated it.

Great, and no problems

The Help & professionalism of Quinn F at etrailer was outstanding. He confirmed that the product was the best choice for my vehicle & purpose, his personal response & follow through impressed me (including an e-mail letting me know my parts were delivered a couple days early). I will definitely be using Quinn F at etrailerfor all my RV related needs.

Still working great, I forget its even there.



by:

The Tekonsha plug-in wiring adapter fit my 99 Silverado 1500 with not any issues at the fuse block. The length of the wire harness allowed me to install the brake controller in the CD storage for easy access and use.



by:

The quality of the adapter and customer service was very good. However, I must have ordered the wrong adapter as this on had an inline 4 plug and my controller had a square plug.

The adapter that you will need for your 2016 Ford 350 is part # 3034-P. Customer Service will reach out to you so that this adapter can be returned.

Etrailer website is easy to use and simple to find what you need. I am really impressed with how fast my item arrived. Great to see the follow up on orders also!

2001 Chevrolet Silverado

Got this for my 2001 Silverado 3500. You can’t ask for anything more simple and self explanatory. Good quality harness. Been in the truck for a year now with no issues at all



by:

Just what I needed. Excellent quality.



by:

Was delivered earlier than anticipated. Had to move one wire to make it compatible with my year truck but not a big deal. Highly recommend Etrailer.com for all your trailer needs.



by:

works great easy to set up and use great investment. It's nice to know what your setting is when adjusting your brake



by:

This made the installation very easy, it was plug and play with this.



by:

Makes install simple. Has been working perfect.



by:

Replacement for another brake controller.
Easy
install. The new cable got rid of excess from previous install.
Both work great and it made a much neater job. As you can see, you can't even tell where the cable comes out of the fuse box!!



by:

Because my truck has the factory tow option, I was able to purchase this custom harness from etrailer for a very quick install. No wires to trace…. No splices…. Very simple. One end of the harness plugged in to a socket under the dash of my truck. The other end of the harness plugged into a socket on the back of the Teconsha P3. Wiring complete!!



by:

A customer service Representative by the name of Rob checked into my order when it did not show up on the estimated date then called me when it got here to let me know it was delivered. Great courteous service and the components worked and installed in a breeze.

Took about 10 minutes to install on my 2000 Chevy Silverado. Plug and play.

Perfect fit on my 2004 GMC SIERRA 1500. Works great and shipping was FAST!



by:

Great product and it is exactly as it is described. I have a 15000lb fifth wheel and I need to be able to control it! I am positive that I bought the right product for that task. Stuyvesant, NY



by:

It doesn't get any simpler than this! Called etrailer and told them what vehicles I had. Sara looked it up and three days later I had the parts. Took all of 10 minutes to install and then I went to pick up my new camper. Product worked just perfect. Great company!

2002 Chevrolet Silverado

I had purchased an electric brake controller to install on my 2002 Chevrolet Silverado 1 ton. I am pretty tech savvy but the thought of wiring into my truck’s electrical system made me a little apprehensive. The thought of my trailer passing me on the road was very thought provoking. Then along comes the “Plug-in” adapter for the brake controller. A no-brainer. Plug into the controller, plug into truck fuse panel (in a specific marked location for the plug), and your ready to go. As I said, a no-brainer



by:

Quality part. Just plug it in and go. No problems yet.



by:

Fast shipping and very easy install with the additional wiring harness. Will buy again



by:

Makes installing easy and quick

1999 Chevrolet Suburban

etrailer's instructions and videos are awesome.
installation
was a breeze UNTIL I needed to locate the brake signal wire (cold side of brake switch) on my 1999 suburban. What a pain. the switch is not very accessible let alone there are a ton of white wires under the dash --along with an alarm.
Long story short, I found this in a GMC forum and it saved me big time:

"Under the dash, next to the emergency brake is a black convenience box. At the bottom of the box is the letters GRN, next to that is the letters NAT with a small recessed box with two male spade connectors. The spade on the right goes to the brake switch. The wire from the brake controller is terminated there."

Using the supplied probe tester I was able to verify this and finished up my installation. The Tekonsha Prodigy P3 controller works great.

The Tekonsha Prodigy P3 controller is still working great. I cant believe i didnt get one sooner. Easy to adjust on the fly and no issues at all.



by:

The wiring connector from the brake controller to the factory truck wiring was a perfect match, Plug and play. The quality of the whole adapter from the wire to the connectors are first class. It saved me a lot of time from laying on my back trying to make wiring connections like I have done in the past. This plug allows me to swap my Tekonsha Prodigy 2 from my other truck in seconds.

I highly recommend this product to everyone that wants a first class product and friendly awesome service from the folks at e trailer. I am a return customer and plan to be one as long as I need trailer parts and accessories.

Everything is still working fine. I expect nothing less from etrailer. You have saved a lot of time with the products I have purchased from you.

  • Weight Distribution & Trailer Brake Controller For Towing 2021 GD XLS 22RBE w/2002 Silverado 1500
    Yes, you will be okay to tow the 2021 Grand Design XLS 22RBE with your 2002 Chevrolet Silverado 1500 with the 5.3L and tow package. The lowest towing capacity according to your owners manual for any 1500 with the 5.3L is 7,000lbs. I recommend using the Equal-i-zer Weight Distribution System # EQ37100ET to tow your Grand Design. This weight distribution system has earned a reputation of being one of the best systems available. It is made in the USA with a lifetime warranty and fits trailers...

  • Parts Needed to Install the Prodigy P3 Brake Controller on a 2002 Chevy Silverado K3500
    To install the Tekonsha Prodigy P3 # 90195 on your 2002 Chevy Silverado K3500 you need the Wiring Adapter # 3025-P which plugs in under your driver-side dash (see attached install video). If you already have the factory plug at the back then you're good to start towing, otherwise you need to check above your spare tire for the OEM wiring. If you find a bundle of wires you'll need the Pollak Kit # PK11898, but if you find a connector instead then you just need the Hopkins # 30955 and you'll...

    The brake controller I would recommend for your 2001 GMC Sierra is the Tekonsha Prodigy P2 Proportional Brake Controller, part # 90885. The Prodigy 2 brake controller is our best selling model. It can be mounted in a 360 degree vertical range and will level itself automatically. It is a proportional brake controller which means that the brakes are applied to the trailer at the same time and same strength as the brakes on your vehicle. It can be used on trailers that have up to 4 axles (8...

  • Brake Controller Stoplight Switch Circuit of 2001 GMC Sierra 2500 Not Working
    This is a pretty common issue for GM trucks around the age of yours. It's the third brake light fuse of your 2001 GMC Sierra 2500 that is blown. When it goes the brake controller activation circuit stops working as well. You can test this really easily by pressing the brake and seeing if the third brake lights up on cab above truck bed.

    It sounds like there is an issue with the stop light switch connection on the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 in your 2002 Chevrolet Silverado 2500HD. The most common problem that causes this connection issue is a blown Center High Mounted Stop Lamp (CHMSL) fuse which is in the engine bay fuse block.
